Shutter Delay – best model to minimize

I am looking to buy a new mid range compact digital camera. One of the main requirements I have is low shutter delay. I have a 10D with zero delay, but it is not practical for me to carry it all the time and the wife does not like to even use it at all.

On looking at the reviews and comparison options, I did not see a selection on shutter delay. Any suggestions where I might find more information no this topic?
